To all whom it may concern:

Be it known that I, ORSON J. BLAKESLEY, a citizen of the United States, residing at the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Keyless Locks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference markedthereon, which form a part of this speciiication.

My invention relates to improvements in locks of the class in which keys as ordinarily understood are not l5 employed. It also belongs to the class of locks in which a number of instrumentalities must be actuated in order to release the bolt or other locking part.

My present invention as illustrated in the drawing and herein described is more especially intended for use as a bicycle lock and is of such construction that the user may operate it in the dark without any difficulty.` This device as shown in the drawing is made in circular form. One end of a chain is secured thereto while to the other end oi the chain is attached'a bolt 2.5 or device which when inserted in the casing is automatically locked in place. A series of p ins protrude from the periphery of the circular casing and the mechanism may be so set as to require that certain of these pins must be pressed in order to release the bolt or hasp.

The mechanism is so constructed that the predetermined pins must be alone pressed in order to release the bolt; while if other pins are pressed the device will only be more securely locked. From what has already been said it will be understood that the mechanism 3 5 may be set for any desired combination, making it necessary that the person who opens the lock must understand this combination.

Having briefly outlined my improved'device as well as the function it is intended to perform, I will proceed to describe the same in detail reference being made to the accompanying drawingr in which is illustrated an embodiment thereof.

In this drawing', Figure 1 is a top plan view oi my improved device. Fig. 2 is an edge view of the same.

Fig. 3 is a horizontal section taken through the casing with the top plate removed. This section is taken between the stationary and movable disks of the lock mechanism with the parts shown on a larger scale than in Figs. 1 and 2. Fig. 4 is a cross section taken on the line IHLI Fig. 3, the pins, however, being shown in elevation. Fig. 5 is a top plan view oi the device similar to Fig. 1 but with the top plate partly broken away and the depending lip thereof sectionized.4 Fig, 6 is a section taken on the line (3 6 Fig. 7 with all of the parts Ireceive studs 12 fast on the cap 7.

in place. Fig. 7 is a plan view of the body of the cas- 55 ing` with all ofthe mechanism removed except the revoluble ring for locking the cap in place. Fig. 8 is a de tail view partly in section oi the movable disk. This is an underneath view of the disk or shows the same with its lower face turned upwardly or in the position the reverse from that shown in Figs. 4, 5 and 6, but on the same or approximately the same scale. Fig. 9 is a perspective view in detail and on a larger scale oiv one of the spring-actuated tumblers or pieces which must be actuated in order to unlock the mechanism. Fig. 10 65 is a ragemtary detail view of the movable disk. Fig. 11 is a similar view of the same viewed from a different position.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate a casing which incloses the lock mechanism. This casing as shown in the drawing is circular in shape and provided with two flat laces. It is in reality composed of two members, G being the body member and 7 a cap. The body of 75 the casing is provided with a circular outer wall 8 interiorly shouldered as shown at 9 to receive the outer edge of the cap '7. The bodyloi the casing is also provided with an annular iiange 10 which is provided at two opposite points with sockets 11 open at the top to 80 Surrounded by the annular flange 10, is a disk 13, which is secured to the body of the casing by a pin 14. This disk is provided with a central opening through which passes a post l5. The disk is also provided with radial slots 16 termi- 85 nating at their inner extremities in an annular recess 17 surrounding the post 15. These slots 16 iorm guides for the inner reduced extremities oi pins 18 whose outer extremities 19 protrude exteriorly from the peripheral wall 8 oi the body oi the casing. Inside ofthe 90v wall 8 each pin is shouldered as shown at 20 and its reduced portion 2l is surrounded by a coil spring 22 located between the shoulder 2O and the annular flange 10 oi the body of the casing. The tendency of this spring 22 is to hold its pin 1S at its outward limit 95 oi' movement. Each pin is provided adjacent the shoulder 20 with a stop 23 which limits the outward movement oi the pin in response to the recoil of the spring 22. The parts 19 and 21 of cach pin 18, fit closely in openings formed in the peripheral Wall 8 100 and the annular flange 10 respectively, of the body ol the casing. Protruding inwardly beyond the annular flange I0, cach pin is provided with a shouldered part 24 and beyond this shouldered part is the reduced portion 25 which enters a slot 1G of the disk 13. The 105 shoulders 26 of each pin limit the inward movemcnt thereof in response to inward pressure on the protruding head 19 oi the pin. Certain of the pins 18 are provided with detachable projections 27 located substantially on the line between the parts 24 and 25 whereby each projection when its pin is forced to its inward limit of movement, enters a slot 28 formed in a movable disk 29. These slots 28 are enlarged at their inner extremities as shown at 30, there being as many slots 28 in the disk 29, as there are slots 16 in the stationary disk 13.

Located in front of the inner extremities of` certain of the pins 18, are what I will term .tumblers 31 having reduced lower portions 32 adapted to fit into the radial slots 16 of the disk 13. The central recess 33 of the disk 29 is considerably larger than the central recess 1.7 of the disk 13. The upper enlarged portion 34 of the tumblers 31, is adapted to enter the recess 33 of the diskA 29 when the pins 18 corresponding with the tumblers 31 are pushed inwardly. Normally the outer extremities 35 of the tumblers which are beveled for the purpose, enter the enlarged inner extremities of the slots 28, and lock the disk 29 from movement. The pins 18 which act upon the tumblers, are not provided with the removable projections 27. 1n other words when the tumblers 31 are placed in position forward of certain of the pins 1.8, the projections 27 which are preferably composed of screws, are removed. The normal position of the pins 18 is such that the projections 27 do not enter the slots 28 of the removable disk 29. As just stated, however, the normal position of the pins 18 is such that the outer extremities of the tumblers 31 are allowed to enter the slots 28 of the disk 29, The tumblers are held at their outer limit of movement, by means of coil springs 36 which surround the reduced inner extremities 37 of the, tumblers 31. These springs are located between the shoulders 38 on the tumblers and the post 15 of the body of the casing.

As the pins 18 which act on the tumblers 31 are moved inwardly, the tumblers are actuated sufliciently to disengage them from the slots 28 of the disk 29, whereby the latter' is free to move or turn on the post 15 within certain limits. The disk 29 is provided with an arm 39 which projects outwardly, terminating just within the peripheral wall 8 of the casing, This arm is provided with a leaf spring 40 one portion of which acts on a dog 41 movably mounted in an opening formed in the arm 39. This dog 31 is held in place by a pin 42 passing through a slot 43 formed in the dog. Another part of the spring 4t), passes-around the outer extremity of the arm 39 and stands out from the arm as shown at 44 but occupying a lower plane than the protruding extremity of the dog 41. The arm 39 is provided with a recess 45 in which the protruding extremity of the dog 41 and the spring part 44 are located.

The disk 13 is provided on its under side with a circumferential recess in which is located a ring 46 having exteriorly protruding lugs 47 adapted to enter the sockets 11 of the annular flange 10 and engage circular grooves 48 formed in the studs l2, whereby the cap 7 is locked in place on the body of the casing. In order to permit the ring 46 to be manipulated from the outside of the casing, this ring is provided with an arm 49 whose outer extremity protru des through an opening formed in the peripheral wall of the casing, this protruding extremity occupying a position below a depending projection 50 attached to the cap, this projection 50 occupying a position fiush with the outer surface of the Peripheral wall 8. This projection 50, however, does not fill the opening in the peripheral wall of the casin g since sufficient space is left below it for the arm 49 which is accessible from the outside; and for the bolt 54 as hereinafter explained. This protruding extremity of the arm 49 is notched or toothed as shown at 5l to facilitate manipulation. When the ring is moved to the position shown by dotted lines in Fig. 7, the cap is unlocked and may be removed whereby the interior mechanism of the lock casing is exposed.

n As shown in the drawing a chain52 is secured to the outer wall of the easing as shown at 53. To the opposite extremity of this chain is attached a bolt 54 having an opening 55 adapted to receive the protruding extremity of the dog 41, when the bolt is inserted through an opening left in the peripheral wall of the body of the casing therefor. This bolt when in position prevents the movement of the arm 49, hence the cap cannot be released bythe ring 46, until after the device has been unlocked and the bolt removed. When it is desired toinsert the bolt, the arm 49 of the locking ring must be in the position shown in Fig. 3 or in the position to lock the cap in place, since thedepth of the bolt 54 is equal to the entire depth of the opening in the peripheral wall of the casing in which the bolt is inserted. When the bolt is in position as shown in Fig. 5, the dog 41 enters the recess 55, while the part 44 of the spring is placed under tensionv by the solid portion of the bolt. The tendencyv of the part 44 oi the spring acting on the bolt which forms an abutment, is to move the disk 29l away from the bolt in the direction to release the latter from the dog 41. This it cannot do, however, as long asfthe tumblers 31. are in their normal position or engaging the inner extremities 30 of the slots 28 formed in the disk-29 as heretofore explained, When, however, the pins 18 corresponding with the tumblers 31 are pressedf inwardly whereby the tumblers are actuated sufficiently to release their extremities'35 from the slots 28 of the disk 33, the spring part 44 acts on the bolt 54' to turn the disk 29 sufficiently to cause the dog 41 to release the bolt 54. A leaf spring 56 now acts on the inner extremity of` the bolt 54, with sufficient force to throw the Abolt automatically out of the casing. When the disk 29 is thrown to the position to release the bolt from the dog 41, the arm 39 of the disk is brought into engagement with a spring 57 which is placed under sufficient tension to return thc disk 29 to its normal position as soon as the bolt 54 is thrown out of the casing as heretofore ex-v plained. As soon as the bolt 54 escapes from the casing,

the pins 18 which have been forced inwardly to operate the tumblers, are released from pressure. When'this is done the tumblers of the lock are actuated by their springs 36 to cause the tumblers to engage the enlarged portions 30 of the slots 28r belonging to the disk 29, thus locking the disk against movement in response to the tension of the spring part 44.

From the foregoing description the use and opera-tion of my improved lock will be readily understood. When a chain is used in connection with the lock, the chain is passed through or around the article to be protected or connected therewith in any suitable manner, after which the bolt 54 is inserted to the position shown in Fig. 5 whereby the dog 41 enters the opening 55' of the bolt, the latter acting on the spring part 44 to place the latter under tension. NoW'i it is desired to release the bolt, the pins 18 in line with the several tumblers 31, are pressed inwardly whereby corresponding movement is imparted to the tumblers of sufficient degree to release the disk 29 allowing the tension of the spring part 44 to move the disk sutliciently to release the bolt from the dog ll. As soon as this occurs the leal spring 56 acts on the bolt with sui'licient force to throw the latter out ol the casing. The movement oi the disk 29 has been sufficient to cause its arm 39 to engage the spring 57 and place the latter under suflicient tension to return the disk to its original or locking` position and when thr tumblers 31 again engage it in the locking relation.

The tumblers 31 are readily removable whereby the combination of the lock may be changed at any time desired. In order to accomplish this it is only necessary to remove the cap 7 and the disk 29 which makes the tumblers accessible. When any tumbler is changed from its position in iront oi one pin to its position in another pin, the screw projection 27 is removed from the pin which is to actuate the tumbler and inserted in the pin from which the tumbler has been removed. It is evident that one or moro oi the tumblers may be changed at pleasure thus requiring the inward movement oi different pins in order to release the looking disk. When these tumblers are changed it is only necessary for the user to take note of the particular pins required to be pressed in order to actuate the tumblers. The locking disk and cap are then replaced in their respective positions when the lock is ready for use.
